forms are regularly alternatingly developed, as to other species, it has 

 been proved that the propagation depends almost alone on the Mo- 

 nilia, the ascigerous stage being somewhat accidental.

Further the six following species of Sclerotinia on Vacciniaceae are 

 corresponding to Monilia-forms to which no special names are given, 

 they are: Sclerotinia megalospora, urnula, oxycocci, baccarum, rhodo- 

 dendri and ledi. 



The species of the subgenus Eusclerotinia produce sclerotia in all 

 parts of the host-plant, in roots, stems, leaves and fruits; the sclerotia 

 are rounded and they only partly assume the shape of their surroun- 

 dings. The propagation takes place by means of the ascospores, the 

 growth of the mycelium plays, however, rather a considerable part in 

 this section; the conidia which are either produced by the sclerotia 

 itself or by the mycelium in the host are described as incapable of 

 germinating, their significance is still unknown; several of the sclerotia 

 have received special names; I shall state the more common species:
